CAR-TRUCK.

SPECIFICATION forming part of Letters-Patent No. 658,786, dated October 2, 1900.

Original application filed February 26, 1900, Serial No. 6,534. Divided and this application filed May 7 1900. Serial No. 15,815. (No model.)

To all whom it may concern:

Be it known that I, GEORGE I. KING, a citizen of the United States, residing at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Oar-Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the to same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevational view. Fig. 2

' is an end elevational view, partly in section;

and Fig. 3 is a plan view of the sand-board or spring-plank.

This invention relates to a new and useful improvement in car-trucks, the object being to provide a truck with an improved form of sand-board or spring-plank so cooperating with the bottom arch and tie bars that a most rigid structure results.

With this object in view the invention consists in the construction, arrangement, and

2 5 combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

The construction shown in this application is found in an application entitled Hopperbottom car, filed by me February 26, 1900, Serial N 0. 6,534, of which this is a divisional application.

In the drawings the truck, with the exception of the spring-plank, is of well-known 3 5 construction, and consists of the usual parts such as are commonly employed in devices of this character. The arch-bars of the truck, however, instead of being made of rectangular-shaped iron are preferably made up of .0 channel-bars.

99 indicates the top archbars of the truck, and 100 the lower arch-bars. The heads of the column-bolts 101 are received in the channel of the top arch-bars, and thereby pre- 5 vented from turning. The nuts on the lower ends of the column-bolts impinge against the usual tie-bars 102, arranged beneath the lower arch-bars and tying the lower ends of the journal-boxes in position.

103 indicates a plate formed with raised the plate, as shown in the drawings, or a cleat of the proper size may be riveted to the upper face of the plate and extend into the channel of the lower arch-bar and serve the same purpose as the integral rib 104.

105 indicates parallel angle-bars riveted to the plates 101, said angle-bars being braced by lattice-work 106 for the purpose of adding strength and rigidity to the structure, at the same time saving weight. The springplank (shown in Fig. 3) as an entirety is very rigid and has a bearing of considerable extent along the lower arch-bars on each side of the truck. The connection between the spring-plank and the lower arch-bars is such that absolutely no play is permitted between the parts, and a most rigid truck-frame results. In fact, the ribs 104 may be termed keys, and the channels in the lower archbars key-seats, which makes a very strong joint and a very desirable one in that it is simple, not liable to get out of order, and the parts are easily assembled.

Having thus described my invention, what i I claim, and desire to secure by Letters Patent, is

1. In a car-truck, the combination with the top and bottom arch-bars made of channeliron, the heads of the column-bolts being received and locked in the channels of the top arch-bars, and a spring-plank formed with continuous raised ribs at its ends which are seated in the channels of the lower arch-bars, said continuous ribs extending laterally beyond the column-bolts and entirely filling the channel between said bolts; substantially as described.

2. The combination with the lower archbars of a truck, said arch-bars being formed with grooved lower faces, of a spring-plank consisting of plates 103, provided with raised ribs 104 received by the grooves in the lower 5 arch-bars, angle-bars riveted to the plates, and cross-braces or lattice-work 106 riveted to said angle-bars; substantially as described.

3. The combination with the lower archbars of the truck, said arch-bars being formed 100 prising parallel angle-bars having latticework between them, and plates secured to the ends of said bars for attachment to the side frames of the truck; substantially as de-. scribed.

In testimony whereof I hereunto aifix my signature, in the presence of two witnesses, 20

this 26th day of April, 1900. v

GEORGE I. KING.
